Water Rocket Launch

Hi everybody ! Today I will talk about a new thing, today I will talk about water rockets. Water Rockets consists in a base built with PVC pipes, a soda bottle and an air pump. You can see the schema of a water rocket below


The following link there is a more detailed description on how to build your own launch base. Water rockets are really fun and you can learn a lot from them. There is a cool water rocket video bellow and it should have taken a lot of time from the guys who built it.



And bellow you can see our less powerful but even cool water rocket that looks like more with a coke bottle than with a rocket



Well that's it for today, see you in the next post !

Last Week in Brasil !!

Hi Everybody,  just one week lasting and my visa arrived !! I will get it in the consulate on Monday and I hope it lasts more than one year, because all my friends took visas for just one year, so they will have to renew it next year and I don't want to do the same.

This week I finally finished my Physics Simulator using OpenCL and OpenGL interoperability. It is called CLGLSim and by now it just simulates particles interacting under gravitational force, but I want to implement also electromagnetism equations and be able to simulate many other physical systems using particles. There is a video of CLGLSim in action colliding two galaxies below.


This video was taken in a dual core x86_64 computer and I would like to run it on a GTX 680 or on a HD 7970 to be able to use the tera flop capacity of these GPGPUs and to see what CLGLSim can do. If you are reading this post and have a graphics card or another OpenCL device try to run the CLGLSim and tell me the results. The source code of CLGLSim is available for free at https://github.com/tlgimenes/CLGLSim and it currently runs in Linux and Windows, but if somebody asks I can write a version for OSX too.
This is a cool simulator and it is pretty good to see the particles moving in a gravity field.

Well, this is it for today, and I need to fill some forms yet and get ready because next week Je vais etre en France !!!

Au revoir !

Visa Taken

Hi everybody ! Today I went to the French embassy to take my visa and everything worked well. I will have to return there mid January the get my passport back. The French embassy is at Paulista avenue and today it was happening the São Silvestre marathon that started when I arrived to the embassy. It was pretty cool to see those people running dressed up like superheroes and many other things.
São Silvestre street race in São Paulo.

The São Silvestre street race is one of the most famous street races in the world and started in December 31, 1925 and it has never been interrupted during its history, not even for the duration of the World War II.
I would like to wish a happy new year for everybody and that 2013 will be an exciting year with many things to study, to visit and many new friends !

Last month in Brazil !!

Hi everybody !! This is my last month in Brazil and I still have a lot of forms to fill and I have to take my visa yet !!
My admission letter is about to arrive and I need it to take my visa, at least I completed the cycle at Campus France.
The last month is something strange, at the same time that  I want to arrive soon at France to meet my new friends and my new school I still have to say goodbye to many people that I would like to see and that I will miss next year, like my parents and the guys that live with me at Campinas.

First Post

This is the first post and the preparatives in Brazil have already begun. I'm still filling out the endless papers and by now I'm far from finishing then.
My flight is booked for 28 January 2013 and I'm pretty exited about the whole thing and I can't wait until I know my new friends.
What is sad about going to study in another country is to leave all of my friends and family here, but life goes on and I hope that the level of "awesomeness" of France will be very high !
